5,703,210 | 5,703,211 | Java: enough free heap to create an object? | <p>I recently came across this in some code - basically someone trying to create a large object, coping when there's not enough heap to create it:</p>
<pre><code>try {
// try to perform an operation using a huge in-memory array
byte[] massiveArray = new byte[BIG_NUMBER];
}
catch (OutOfMemoryError oome) {
// perform the operation in some slower but less
// memory intensive way...
}
</code></pre>
<p>This doesn't seem right, since Sun themselves recommend that you shouldn't try to catch <code>Error</code> or its subclasses. We discussed it, and another idea that came up was explicitly checking for free heap:</p>
<pre><code>if (Runtime.getRuntime().freeMemory() > SOME_MEMORY) {
// quick memory-intensive approach
}
else {
// slower, less demanding approach
}
</code></pre>
<p>Again, this seems unsatisfactory - particularly in that picking a value for <code>SOME_MEMORY</code> is difficult to easily relate to the job in question: for some arbitrary large object, how can I estimate how much memory its instantiation might need?</p>
<p>Is there a better way of doing this? Is it even possible in Java, or is any idea of managing memory below the abstraction level of the language itself? </p>
<p><strong>Edit 1:</strong> in the first example, it might actually be feasible to estimate the amount of memory a <code>byte[]</code> of a given length might occupy, but is there a more generic way that extends to arbitrary large objects?</p>
<p><strong>Edit 2:</strong> as @erickson points out, there are ways to estimate the size of an object once it's created, but (ignoring a statistical approach based on previous object sizes) is there a way of doing so for yet-uncreated objects?</p>
<p>There also seems to be some debate as to whether it's reasonable to catch <code>OutOfMemoryError</code> - anyone know anything conclusive?</p>

819,604 | 819,605 | Is using strings this way inefficient? | <p>I am a newbee to c++ and am running into problems with my teacher using strings in my code. Though it is clear to me that I have to stop doing that in her class, I am curious as to why it is wrong. In this program the five strings I assigned were going to be reused no less than 4 to 5 times, therefore I put the text into strings. I was told to stop doing it as it is inefficient. Why? In c++ are textual strings supposed to be typed out as opposed to being stored into strings, and if so why? Below is some of the program, please tell me why it is bad.</p>
<pre><code> string Bry = "berries";
string Veg = "vegetables";
string Flr = "flowers";

4,559,578 | 4,559,579 | jQuery - detect mouse out of new element | <p>I've built a menu using jQuery which shows a new element fading in when the user hovers the mouse over the element and fades it out when they move the mouse away. Now, I've moved the element up so it covers the original element which is causing the problem that the second hover event is triggered when the new element is placed over the top. What would be the best method to ignore the new element and only fade out once the mouse has moved out of the bound of the original element?</p>
<p>Here's the code:</p>
<pre><code>$('#menuitem').hover(function() {
$('#menu').append('<span id="hover_'+$(this).attr('rel')+'" class="hover"></span>');
}, function() {
$('#hover_'+$(this).attr('rel')).fadeOut(function(){$(this).remove();});
});
</code></pre>
<p>Now, the <code>#menu</code> item is a anchor with some text in it, when the mouse is over it, a new element (<code>.hover</code>) should appear on top and should fade out once the mouse leaves the original menu item.</p>
<p>What's currently happening is that the new element appears and fades out immediately as the second hover function is triggered when the new item is added on top of the original anchor.</p>
<p>Thanks,

1,357,701 | 1,357,702 | Am I failing to follow the standard? | <p>If I have something like this:</p>
<pre><code>MyStruct clip;
clip = {16, 16, 16, 16};
</code></pre>
<p>I get the following warning from the compiler:
warning: extended initializer lists only available with -std=c++0x or -std=gnu++0x</p>
<p>If I active -std=c++0x in the compiler, it does not give any warning. But I'm not sure if I am following the standard. So should I deactivate that flag and initialize each member of the structure separately?</p>
<p>Thank you.</p>

470,517 | 470,518 | Why does iterating over jQuery objects with .each() not give me jQuery objects? | <p>The following works as expected:</p>
<pre><code>$(".foo").first().text("hi!")
</code></pre>
<p>...because <a href="http://api.jquery.com/first/" rel="nofollow"><code>first()</code></a> returns a jQuery object.</p>
<p>However, if I want to work with the <a href="http://api.jquery.com/text/" rel="nofollow"><code>text()</code></a> method for all matches, I need to do:</p>
<pre><code>$(".foo").each( function(idx, obj) {
$(obj).text("hi!")
}
)
</code></pre>
<p>...because <a href="http://api.jquery.com/each/" rel="nofollow"><code>each()</code></a> gives you DOM objects.</p>
<p>What is the design reason behind this baffling difference? How can I avoid having to build a jQuery object for each match?</p>

<p>Is it a good idea? How would I design such a service? All suggestions are welcome</p>

<p>Here, based on what <code>$this</code> is, I need to call function example. So if <code>$this = 1</code>, I need to call <code>example</code> thrice - <code>$a</code> value <code>1, 4, 7</code>. If <code>$this = 2</code> I need to call it once, value <code>3</code>.</p>

2,896,836 | 2,896,837 | Dispose C# DLL marked for COM interop | <p>I created a vanilla C# dll and marked it for COM inter op. The dll is a plain user form with no functionality as this is an experiment. </p>
<p>I registered the DLL and opened active x test container and instantiated my COM object. It shows up in the test container and i can view the exposed methods of the control - these are the default methods and not created by me.</p>
<p>i then exit from the active x test container and i noticed that test container was still lurking around in task manager and that i had to kill the process manually. This leads me to believe that the test container still holds a reference to my C# dll exposed for com inter op. </p>
<p>The default dispose method in the designer.cs is</p>
<pre><code> protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
</code></pre>
<p>When i used the test container with Quick time, it invoked quick time as expected and when i closed the test container it disposed correctly and did not leave a footprint in the task manager.</p>
<p>The question - is there a specific thing that i must do in my dispose method? Also, this may not be relevant, but when i create a test project and it launches my c# control and i click on the close button, it closes my test form but the test application ins still running in debug mode - the run button is disabled.</p>

<p>Also there doesn't seem to be a way to construct a NameValueCollection that acts as a query string editor. Is there one? If not, why? Being able to edit query strings is a pretty useful thing, but this functionality is totally hidden away in an obscure mode of some object most people don't even know exists.</p>

6,023,143 | 6,023,144 | CountDownTimer runs in old Activity when switching Activities | <p>I have a CountDownTimer, which needs to run all the time. There are 2 Activities (A and B). Activity A has the CountDownTimer, which updates a TextView inside it. When I switch to B, the CountDownTimer still runs (it is the desired behavoir), but when I switch back to A, there seems to be an old and a new A. The timer does not update a TextView inside of the "new" A. It is started only once when A is first visited. Any ideas of how to solve this problem? Maybe put the timer somewhere else?<br>
<strong>Edit:</strong> Some code: </p>
<pre><code>private void prepareTimer() {
// TODO: DOES NOT WORK YET! (switching activities -> runs in old activity)
textTime = (TextView) findViewById(R.id.text_time); // is a field

2,025,687 | 2,025,688 | How to avoid data lose when UIImagePickerController unloads my controller? | <p>I am using UIImagePickerController to take a photo from the camera. However, the I find that randomly my calling controller (the one that is shown before the UIImagePickercontroller is shown) gets unloaded. I logged the viewDidUnload, and indeed it does get called. When the camera is done and dismissed, my controller's viewDidLoad will be called, unfortunately all the state is now gone. Things like text entered or things selected will be gone. </p>
<p>Obviously this is something to do with running out of memory. But is this behavior normal? Should I be handling it? This is NOT typically how modalViewController works. Usually you show it and dismiss it, everything should be intact. </p>
<p>What is a good way to avoid data lost in this case? Should I have to write a bunch of code to save the full state?</p>

3,150,512 | 3,150,513 | question regarding the keyword super | <p>In the book "Java in a Nutshell", chapter 3, section 3.5 Subclasses and Inheritance, there is such as paragraph about the usage of super to access overriden method:</p>
<blockquote>
<p>Note that the super keyword invokes the most immediately overridden version of a method. Suppose class A has a subclass B that has a subclass C and that all three classes define the same method f( ). The method C.f() can invoke the method B.f( ), which it overrides directly, with super.f( ). But there is no way for C.f() to invoke A.f( ) directly: super.super.f( ) is not legal Java syntax. Of course, if C.f() invokes B.f( ), it is reasonable to suppose that B.f( ) might also invoke A.f(). This kind of chaining is relatively common when working with overridden methods: it is a way of augmenting the behavior of a method without replacing the method entirely. We saw this technique in the the example finalize() method shown earlier in the chapter: that method invoked super.finalize() to run its superclass finalization method.</p>
</blockquote>
<p>What does it mean? There is no way for a instance of class C to call the f() of class A? Why?</p>
